Turbopower™ Turbodrills

Lower your cost per foot in hard and abrasive environments

Turbopower™ turbodrills help you maximize your asset value in hostile drilling environments by reducing well time and lowering your cost per foot. Especially suited for hard and abrasive formations, Turbopower turbodrills are matched with TurboForce™ diamond-impregnated bits, so you can reduce tripping for worn bits. The all-metal design helps you achieve longer runs with consistent power and eliminate elastomer breakdown in high-temperature environments, thus avoiding NPT.

Turbopower turbodrills improve drilling performance so you can reach TD in one run:

Operating in a well containing highly abrasive sandstone, the operator’s primary objective was to drill vertically through an approximately 1,100-ft (335-m) production section in two runs, with one trip out to surface planned for replacing the bit.

Halliburton’s Turbopower turbodrills application in Qatar. The results confirmed that using this solution to drill these
hard formations can be an economical approach with no compromise to safety, steerability, or hole quality.

Halliburton successfully reduced drilling days and delivered significant cost savings using Sperry Drilling service;s Turbopower with Drill Bits and Services diamond impregnated bit for drilling the first of eight deep wells an operator planned to drill in a remote location in India.

In this well, the operator challenged Sperry Drilling services to provide a solution that would achieve the necessary build rate in the curve to land the well at proper depth, and drill the lateral section with minimal directional corrections – drilling both sections as fast as possible while delivering good hole quality.

In one of the most challenging high temperature applications in Egypt, an operator planned to drill a gas well in the western desert. Their objective was to land the 6-inch hole through the high temperature, very abrasive kaolinite siltstone formation known to cause slow rate-of-penetration (ROP) and tool failure.

The operator of a field in south Bolivia planned to drill a gas well in the South Andean Foothills through a Devonian formation of fractured sandstone, siltstone and shale. The overthrust faults and stressed formations are prone to “bit-sticking” and, typically, it is difficult to maintain the well path in such applications.

The Turbopower turbodrill achieved record footage drilled in the first two runs of 548 meters (1,798 feet) and then 581 meters (1,906 feet) respectively. Overall ROP averaged 1.5 meters per hour (4.92 feet per hour) shaving five drilling days from the plan.

In spite of the poor drillability of the challenging formation, the Sperry Turbopower turbine delivered the fastest ROP in the pre-salt of this field, drilling the 8-1/2-inch hole 348 meters to total depth in 79.55 hours, achieving a field record ROP of 4.4 m/hr and saving the operator three days of rig time.
